The number of survivors after hypoxic-ischemic encephalopathy has been increasing due to recent progress in medical system and care. Impairment after injury ranges from mild memory deficit to vegetative state or death. Cognitive impairment is particularly common in the survivors, because the hippocampus and medial temporal lobe are vulnerable to ischemic insult. Medication and cognitive rehabilitation should be initiated to minimize the impact of various cognitive deficits. Instead of Glasgow-Pittsburgh Cerebral Performance Categories, which is insensitive to functional change, standardized functional assessment tools should also be used in research as well as in rehabilitation settings.

The endocrinologic complications such as adrenal insufficiency and hypopituitarism are common after traumatic brain injury (TBI) portending poor rehabilitation outcome. Anterior pituitary dysfunction presents as hypothyroidism, hypogonadism, growth hormone deficiency, adrenal insufficiency and hyperprolactinemia, whereas posterior pituitary dysfunction includes syndrome of inappropriate antidiuretic hormone and central diabetes insipidus. Careful history taking and physical examination are essential to detect these abnormalities early. Laboratory tests such as serum/urine sodium and osmolality, thyroid hormone, testosterone, estradiol, cortisol, prolactin, growth hormone or IGF-1 are also necessary. Screening of endocrinologic functions is recommended especially in patients with moderate or severe TBI, skull base fracture or diffuse axonal injury 3 to 6 months after injury. Further studies are needed to reveal the effect of early correction of endocrinologic abnormality on long-term functional outcome.

Traumatic brain injury (TBI) is a major cause of long-term physical and psychological disability and death. In patients with TBI, undernutrition is associated with an increased mortality rate, more infectious complications, and worse neurologic outcomes. Therefore, timely and effective nutritional therapy is particularly crucial in the management of TBI to improve patients’ prognoses. This narrative review summarizes the issues encountered in clinical practice for patients with neurotrauma who receive acute and post-acute inpatient rehabilitation services, and it comprehensively incorporates a wide range of studies, including recent clinical practice guidelines (CPGs), with the aim of better understanding the current evidence for optimal nutritional therapy focused on TBI patients. Recent CPGs were reviewed for 6 topics: 1) hypermetabolism and variation in energy expenditure in patients with TBI, 2) delayed gastric emptying and intolerance to enteral nutrition, 3) decisionmaking on the route and timing of access in patients with TBI who are unable to maintain volitional intake (enteral nutrition versus parenteral nutrition), 4) decision-making on the enteral formula (standard or immune-modulating formulas), 5) glycemic control, and 6) protein support. We also identified areas that need further research in the future.

OBJECTIVE: To investigate the effect of repetitive magnetic stimulation (rMS) of the spinal cord on limb angiogenesis in healthy rats and explore its implication for the treatment of lymphedema. METHOD: Twelve adult male Sprague-Dawley rats were divided into four groups as follows: sham rMS followed by tissue harvest 5 minutes later (group 1, n=2), 1 Hz rMS and tissue harvest 5 minutes later (group 2, n=3), 20 Hz rMS and tissue harvest 5 minutes later (group 3, n=3), 20 Hz rMS and tissue harvest 30 minutes later (group 4, n=4). Animals were treated with 20-minute rMS with 120% of the motor threshold on their left side of upper lumbar spinal cord. Expression of angiogenic factors, that is, Akt, phospho-Akt (pAkt), endothelial nitric oxide synthase (eNOS), phospho-eNOS (p-eNOS) were measured by western blot. Bilateral hindlimb muscles (quadriceps and gastrocnemius) were harvested. RESULTS: Expression of Akt in left quadriceps increased in group 4 compared with group 2 and 3 (3.4 and 5.3-fold each, p=0.026). Expression of eNOS in left plus right quadriceps markedly increased in group 3 and 4 compared with group 1 and 2 (p=0.007). Expressions of eNOS, Akt and p-eNOS, pAkt in gastrocnemius were not comparable between four groups (p>0.05). CONCLUSION: Repetitive magnetic stimulation of the spinal cord may exert an angiogenic effect closely linked to lymphangiogenesis. It has clinical implication for the possible therapy of lymphedema caused by breast, cervical or endometrial cancer operation. Future studies with the specific lymphatic endothelial cell markers are required to confirm the effect of rMS on lymphangiogenesis.

OBJECTIVE: To investigate the effects of short-term robot-assisted upper limb training on hemiplegic patients compared to conventional physical therapy. METHOD: This study was a prospective, single-blinded, randomized controlled trial. Eighteen hemiplegic patients due to brain lesions were randomly assigned to: (1) robot-assisted upper limb training and conventional upper limb physical therapy for 30 min a day, respectively (Robot group); or (2) conventional upper limb physical therapy for 30 min twice a day (Conventional group). All interventions were provided for 2 weeks, 5 times a week. Each patient was evaluated at pre- and post-treatment by the Fugl-Meyer assessment-upper extremity (FMA-UE), Jebsen hand function test (JHFT), grip power, modified Barthel index-upper extremity (MBI-UE), line bisection test, and Albert test. RESULTS: The Robot group showed significant improvement in FMA-UE (pre: 13.22 +/- 14.20, post: 21.67 +/- 15.84; p = 0.018), MBI-UE (pre: 14.33 +/- 7.42, post: 16.56 +/- 6.95; p = 0.041), and line bisection test (pre: 25.15 +/- 34.48, post: 14.93 +/- 28.38; p = 0.043). The Conventional group showed significant improvement only in MBI-UE (pre: 9.22 +/- 6.06, post: 15.56 +/- 6.19; p = 0.008). The improvement in MBI-UE was larger in the Conventional group than Robot group (6.33 +/- 3.28 vs. 2.22 +/- 2.49; p = 0.014). CONCLUSION: This study suggests that short-term robot-assisted upper limb training may improve upper limb function in hemiplegic patients. However, proper physical therapy may be needed to transfer improved upper limb function to activity of daily living. In addition, goal-directed reaching tasks using a robot are expected to be a treatment option for hemineglect.

PURPOSE: Basiliximab has become widely used in clinical practice for initial immunosuppression in renal transplantation cases, to reduce the incidence of acute rejection without adverse events. Herein, we report the early outcomes of renal transplantation using basiliximab at a single center. METHODS: This retrospective study included 148 renal allograft recipients at a single center. All patients were followed for longer than 1 year after transplantation, and treated with a calcineurin inhibitor and steroids for maintenance immunosuppression. The use of basiliximab and mycophenolate mofetil (MMF) was optional. We compared the incidence of episodes of acute graft rejection in kidney recipients who were treated with basiliximab as an initial immunosuppressive therapy with those who were treated without basiliximab. RESULTS: Basiliximab was used for initial immunosuppression in 58 patients. Patients maintained immunosuppression with triple (n=69) or double (n=79) regimens including a calcineurin inhibitor (cyclosporine A (n=111) or tacrolimus (n=37)) and methylprednisolone with or without MMF. Thirty-six (24.3%) patients had a rejection episode within 1 year after transplantation and twenty-six (17.6%) patients had an episode of infection. The patients who were treated with basiliximab had fewer rejection episodes (n=11, 18.9%) within the first year after transplantation than the patients who did not take basiliximab (n=25, 27.7%); this difference was not statistically significant. (P=0.245). However, basiliximab significantly affected the number of rejection episodes in the double regimen group (P=0.006), but not the number of rejections in the triple regimen group (P=0.432) and did not affect the number of infection episodes in both groups (P value of double, triple=0.291, 0.772) within one year after transplantation. CONCLUSION: The results of this study suggest that basiliximab might be more useful for graft recipients who are treated with double immunosuppression with a calcineurin inhibitor and steroid than for the recipients with triple immunosuppression including MMF.

OBJECTIVE: To identify the differences in the movement of the hyoid bone and the vocal cord with and without electrical stimulation in normal subjects. METHODS: Two-dimensional motion analysis using a videofluoroscopic swallowing study with and without electrical stimulation was performed. Surface electrical stimulation was applied during swallowing using electrodes placed at three different locations on each subject. All subjects were analyzed three times using the following electrode placements: with one pair of electrodes on the suprahyoid muscles and a second pair on the infrahyoid muscles (SI); with placement of the electrode pairs on only the infrahyoid muscles (IO); and with the electrode pairs placed vertically on the suprahyoid and infrahyoid muscles (SIV). RESULTS: The main outcomes of this study demonstrated an initial downward displacement as well as different movements of the hyoid bone with the three electrode placements used for electrical stimulation. The initial positions of the hyoid bone with the SI and IO placements resulted in an inferior and anterior displaced position. During swallowing, the hyoid bone moved in a more superior and less anterior direction, resulting in almost the same peak position compared with no electrical stimulation. CONCLUSION: These results demonstrate that electrical stimulation caused an initial depression of the hyoid bone, which had nearly the same peak position during swallowing. Electrical stimulation during swallowing was not dependent on the position of the electrode on the neck, such as on the infrahyoid or on both the suprahyoid and infrahyoid muscles.
